Update 2.0 was the tenth major update to Geometry Dash. It was released on 26 August 2015. This update introduced two new levels, Geometrical Dominator and Deadlocked, user coins, a secret vault, lots of new editor features, friending, following and messaging on user account systems, 4 new colours, 14 new cubes, 9 new ships, 10 new balls, 10 new UFOs, 11 new waves, a new robot form with 6 designs and two new trails.

The blue coin in the third WIP image was never seen in the game. It was probably an earlier design of the user coin. It has been replaced with a silver coin with the letter 'C' in it.

In Update 2.0, the wave was briefly renamed to a "dart" in the icon select menu. This was changed back to the familiar "wave" in update 2.01, after receiving much criticism from the community.

In Update 2.01, RobTop made it impossible to cheat on Steam by slowing down the game (speedhacking).

Although the update added unlimited color channels, the game crashes when 1000 different color channels are reached.

The cube used in the Geometrical Dominator sneak peek appears to have a shaded part around it.

On June 16, 2017, Viprin tweeted some images of early concept art for Geometry Dash.[1] The fourth image, which revolves around 2.0's early development, shows early concept art for the robot gamemode which is also shown on the Robot button in the Icon Kit. A new ground based on the Deadlocked tileset was also originally planned for the update.

Previews

18 October, 2014: Robert Topala makes his first, brief mention of Update 2.0 through Facebook, in the Update 1.9 changelog. When touching on the user accounts system that was introduced in 1.9, he says, "Will include more in update 2.0."

15 December, 2014: Topala announces on the official Geometry Dash Facebook page that he would begin sharing information about Update 2.0. He writes, "Highscore system is back online and should be a lot faster than before. More info about the Steam version and Update 2.0 coming in the next few days. Thanks for waiting!".

21 December, 2014: Topala posts his first preview image for the update. The figures on either sides of the picture resemble monsters, and a cube is included in the center. Written above is "The INVASION has begun", and there is also text reading "Update 2.0 W.I.P" in the lower right hand corner. This image caused much hype around the network, and rumours of one of the new songs being Invaders, a song by Waterflame, started to expand.

26 December, 2014: Topala posts his second preview image, showing a Super Mario Bros-like stage, with a background that resembles to the video game Super Mario World. The cube that is included is similar to the 1-up mushroom found in the Super Mario series. It has shading, and is pixelated, hinting the possibility of new icons. It also shows new ground, and background patterns. Also, the 1-up mushroom has 3 colors from the shading, alike the Steamstep, and Companion Cube icons.

13 January, 2015: Topala posts another preview picture, confirming the existence of blue coins, an upcoming feature that was first discovered on the GJ_GameSheet file from Update 1.9 and in the GJ_GameSheet-uhd file from the Steam version. The blue coin closely resemble the regular, yellow coins, which were added in Update 1.6. While no information has officially been released on them, it is widely believed that they will be used for coins in the level editor, due to his post saying "I will add this maybe as user coins..." . The preview image also introduces two new wave icons, and new portals that were discovered to teleport the player to the nearest teleport portal. The colors of the portals are blue, and orange, confirming a Portal reference. About this, he also confirmed for 2.0 unlockable versions for the robot, and a chance for some of Etzer, and Viprin's Utopia texture pack Icons/Balls/Ships/Waves/UFOs to come in future updates.

February 5, 2015: Topala hints that he will post an Update 2.0 promo on the Geometry Dash Lite Update 1.9 change log. He writes, "I will be posting another Update 2.0 promo later today or tomorrow."

13 February, 2015: Topala posts a fifth preview picture, which hints the soundtrack for the upcoming level. It depicts "B + D," an airplane, a skull with a lock on its forehead, a flame rising out of water, and a question mark. It was most agreed on that the next level would be "Deadlocked," by F-777, as B + D = F, the airplane refers to the Boeing 777, and the skull and lock refer to the song name itself. The soundtrack was also not available in the custom music selection. The other song would be an unknown song by Waterflame as the picture of a flame rising out of water hinted.

Blue coins = user coins = separate achievements and rewards". He has also mentioned an upcoming collaboration system, and following creators.

More craziness in 2.1!"[11] He also mentions a changelog which describes the new features of Update 2.0. With the post, he confirmed that the changelog is coming very soon, and he also said that keeping updates smaller with only 1-2 months of development will be better in the future. He also said that 2.1 will be smaller, but faster because 2.0 "took too long". This statement turned out to be false, as 2.1 actually has already taken longer than 2.0.

He also confirmed that he is adding an option which allows users to have up to 100 saved levels: "Hmm, well with the new improvement in save/load times it shouldn't be a problem. I will add an option that you can toggle to allow 100 saved levels (currently the limit is 20)".

1 July, 2015: During a conversation on TouchArcade RobTop said that "Hopefully I will be able to give some more info in a few days. The update is pretty much done, just fixing bugs. When adding many new systems like this there are a lot of things that can break. Trying to make sure you won't have any nasty bugs when 2.0 is released."[17]

6 July, 2015: Robtop posted on TouchArcade that performance of 2.0 is a lot better than 1.90 because of the implementation of 64-bit architecture on iOS: "Things are going well, still not 100% ready though.

Trying to get it done as fast as I can. Thanks for waiting so long, I know it sucks :)"

8 July, 2015: During a conversation on TouchArcade, RobTop mentioned that players can now place blocks from the very start of the level to give players more freedom when designing their levels: "I even removed the limit where you couldn't place blocks too early in a level, now you can place them at x:0."[23].
